            by implementing the member functions <code class="computeroutput"><span class="identifier">size</span><span class="special">()</span></code>, <code class="computeroutput"><span class="keyword">operator</span><span class="special">[]</span></code> via inheritance of base-classes specialized
            by the traversal type of the underlying iterator. This is normally requires
            no alteration of code. It does mean that types that derive from iterator_range
            may need to prefix <code class="computeroutput"><span class="keyword">this</span><span class="special">-&gt;</span></code> to the various member functions.
            Additionally it has been noted that some calling code was relying on
            member functions such as <code class="computeroutput"><span class="identifier">size</span><span class="special">()</span></code> being present despite the underlying
            iterators not being random-access due to <code class="computeroutput"><span class="identifier">iterator_reference</span><span class="special">&lt;</span><span class="identifier">Iter</span><span class="special">&gt;::</span><span class="identifier">type</span></code>
            not being a reference. The suggested refactoring is to use <code class="computeroutput"><span class="identifier">boost</span><span class="special">::</span><span class="identifier">size</span><span class="special">(</span><span class="identifier">rng</span><span class="special">)</span></code>.
